EN A recent transmission scheme called Packet-Appended Bit-Interleaved Coded Modulation with Iterative Decoding (PA-BICM-ID) consists in appending a conventional packet of Gray-labeled signals with some extra non-Gray-labeled signals in order to enable successful iterative decoding at the receiver side. In this paper, PA-BICM-ID is combined with Orthogonal Frequency Division Multiplexing (OFDM) with the aim to combat harmful effects of inter-symbol interference introduced by the selective fading channel. Although both high correlation between fading coefficients on adjacent OFDM subcarriers and long channel coherence time limit the benefits of diversity that can be derived from iterative decoding, the presented results show a reasonable goodput gain of PA-BICM-ID over conventional BICM.
